PIPE-THREAD rnorrncron.

,Application flled March a, 1924. Serial 110,396,503.

This invention relates. to a pipe thread securing lugs to draw it tight on the pipeend.

It will be understood by those skilled in the art that small pipes which can be threaded by hand do not require much precaution to prevent their threaded ends from being injured, or if injured the injury can be easily corrected, but on the larger sizes of pipe an injury to the pipe ends means considerable annoyance and loss since it practically requires the placing of the pipe in a heavy machine to be rethreaded.

The present device is intended both to protect the threads from casual injury as well as to be heavy enoughto act as a stiffening band on the pipe end, the bead ing and inturned flange also acting to stiffen the protector.

Another object of this invention is to provide the protector with indentations which will be roughened on the inside of the protector to engage the threads to prevent the protector from being easily knocked 0d the pipe.

Other objects of the invention will appear as the description proceeds.

An embodiment of the invention is shown in the accompanying drawings in which the same reference numeral is applied to the same portion throughout, but I am. aware that there maybe modifications thereof.

Fig. 1 is an end view of a pipe with the protector applied thereto,

Fig. 2 is a view of a pipe end, in side elevation, with a protector thereon, a portion of it being shown in section, and

Fig. 3 is a view showing the protector before it is beaded or bent to the desired shape,

Fig, 4 is a sectional view through the pro tector at one set of the indentations for holding the protector on the threads of the pipe ends, showing the way the indentations hold the protector in place.

with some rough punched slits or indentations 2 formed therein to aid in holding the band in place on the threads. At one end The protector consists of a fiat band 1 the band has two side recesses 3 and 4 to ""form two laterallyv extending ears 5 and. 6

beveled at 5 and 6'. At the other end the .1 bandv has two holes 7 and 8 and a longitudinally projecting ear 9.

When'the band is prepared for use one edge is flanged down'as shown at 11 and it is headed up at 12 and 13 to give it greater stiffness. Atthis time the ears 5 and 6 are turned outwardly so that when the protector is applied to the pipe end said ears will easily pass through the holes 7 and 8 and may be clinched down as shown in Figs. 1 and 2. The ear 9 is arranged to project over the opposite end between thebeads to aid in holding the protector properly in place. When the band is secured on the pipe and the lugs are hammered down and serve to draw the band tightly down on the pi e.

llvhat I claim is as follows, but modifications may be made in carrying out the invention shown in the drawings and in the above particularly described form thereof,

within the purview'ofthe invention as de- 2. A pipe protector haying a pair of slots at one end and a pair of laterally extending, beveled lugs 'at the other end to draw the protector tight on the pipe when the lugsare passed through the slots and bent down.

3. A protector for pipe threads, compris ing a ,metal band beaded on one edge and flanged on the other and having slots in one end and laterally extending beveled lugs at the other end whereby when the lugs are passedthrough the slots the band will bedrawn tight down upon the pipe.

4. A ipe protector, comprising a band provide 'with a beaded flange, on one edge I and a head on the other and having apair of slots at one end'and'a .pair of laterally extending beveled lugs at the other whereby when the lugs are passed through the slots the pipe -protector can be drawn tight about a pipe end and secured thereto.

5. A protector for pipe threads, compris- 5 ing a metal band beaded and flanged, a pair of lugs on one end of the protector shaped to pull the protector ends together when the lugs are bent down on said protector to secure the ends of the band together on a pipe and pairs of indentations adapted to engage the threads of the pipe to prevent the protector from being knocked ofi.

In testimony whereof I have hereunto set my hand this 19th day of February A. D. 1924:.
